      Server Description

      A high-capacity memory-optimized instance featuring ninety-six vCPUs and seven hundred sixty-eight gigabytes of RAM for demanding in-memory workloads.

      Memory Optimized

      Amazon Web Services r5.24xlarge is a memory-optimized instance powered by the Nitro hypervisor and an Intel Xeon 8259CL processor. It features 96 vCPUs (48 physical cores) running at 3.1 GHz and 768.0 GB of DDR4 memory, providing a high memory-to-core ratio of 8.0 GB. The instance lacks local storage but delivers a baseline network bandwidth of 25 Gbps. Performance benchmarks indicate strong multi-core processing and exceptional memory bandwidth, with cached read speeds of 4503.04 GB/sec and high Redis throughput. Conversely, single-core execution and LLM text generation are weaker. This hardware profile is highly efficient for memory-intensive workloads, such as large-scale in-memory databases, caching layers, and enterprise applications, while avoiding the cost of bundled local storage.

      Workload Profiles

      2.85Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
